Interatomic force constants of semiconductors Original Research Article

Interatomic force constants of AIIBVI and AIIIBV semiconductors have been calculated using plasma oscillations theory of solids. Two simple equations relating the bond-stretching force constant (α) and plasmon energy have been proposed. The calculated values of α have been used in calculating the values of bond-bending force constant (β). Our calculated values of α and β are in excellent agreement with the values reported by different workers.
